Clinical utility of preoperative stress perfusion cardiac magnetic resonance for predicting cardiovascular events in patients undergoing major noncardiac surgery.
Article in Annals of medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAlthough guidelines recommend preoperative stress testing for patients with risk factors, the appropriate indications for stress perfusion cardiac magnetic resonance (CMR) have not been clearly defined. This study aimed to investigate the value of preoperative stress perfusion CMR in predicting major adverse cardiovascular events (MACE) in patients undergoing major noncardiac surgery.
methodsThis study included 309 patients who underwent CMR within 180 days prior to major noncardiac surgery between 2010 and 2022. Patients were categorized based on the presence or absence of inducible myocardial ischemia. The primary outcome was MACE, defined as a composite of cardiovascular death, myocardial infarction, sustained ventricular arrhythmia, heart failure, or ischemic stroke occurring during the indexed hospitalization for surgery or within 30 days post-discharge.
resultsThe mean patient age was 72 years (51% male), and 21% demonstrated inducible myocardial ischemia. Total MACE occurred in 4.5% of patients and was significantly higher in the inducible ischemia group compared to those without ischemia (16.9% vs. 1.3%,
conclusionsIn this retrospective cohort study, inducible myocardial ischemia detected by stress perfusion CMR in patients undergoing major noncardiac surgery was associated with MACE during hospitalization or within 30 days post-discharge. Larger prospective or multicenter studies are required to validate these findings and ensure generalizability.
